Detailed Description

A widget which displays output from a terminal emulation and sends input keypresses and mouse activity to the terminal.

When the terminal emulation receives new output from the program running in the terminal, it will update the display by calling updateImage().

The user interaction needed to create selections will also change, and the user will be required to hold down the shift key to create a selection or perform other mouse activities inside the view area - since the program running in the terminal is being allowed to handle normal mouse events itself.

Parameters
